How to upload map corrections?

carNAVi is continously improving the digital GPS map of the
Philippines and we would like to encourage you to actively help in
getting the maps better by reporting incorrect map and routing data.

Please
select the type of change and describe it as detailed as possible. If
you know the coordinates, please enter them also with your comment. You
may upload your recorded tracks, waypoint files, a screenshot, scetch or
other file to support your report.
